| 摘 要： | 从全球变化的空间观测需求出发,设想了一个依靠载人月球基地的对地观测望远镜,通过模拟地球静止轨道,太阳轨道和月球轨道,利用逐点计算法,从空间、时间和角度三个方面分析月球对地观测的覆盖特点,同时与现有的静止轨道卫星和日地L1点对地观测作比较.分析结果表明,月基对地观测具有良好的时空覆盖性能,尤其是角度覆盖度优点突出,有助于完善多角度遥感以及全球能量平衡观测系统.

| Abstract: | Based on the observation requirement of global change study, the point-by-point method was used to calculate the coverage indicators on the basis of orbit simulation and spherical ground triangulation. Then, a comparison was made among three platforms in space: Geostationary satellite, the Moon and the Earth-Sun L1 point. The result has shown that, though the temporal-spatial coverage from the Moon is only a little larger than that from Geostationary orbit, the moon offers a much better angular coverage, which is of great significance to the multi-angle remote sensing and the observation system to detect the Earth's energy balance. |
